History ASU/NASA Space Grant Program  Principle of the telegraph discovered, but not battery-powered.  Then in 1753 a certain C.M. in Scotland devised a signaling machine that used an insulated wire for each letter of the alphabet.  Luigi Galvani notices the reaction of frog legs to voltage  Alessandro Volta publishes details of a battery.  The Daniell Cell. A British researcher John Frederich Daniell developed an arrangement where a copper plate was located at the bottom of a wide-mouthed jar.  1898 to The Edison Battery. Thomas Edison, the most prolific of all American inventors, developed an alkaline cell with iron as the anode material (-)and nickel oxide as the cathode material (+).  The zinc-mercuric oxide alkaline battery by Ruben.  1964 – Duracell was formed (incorporated)

ASU/NASA Space Grant Program How does it work?

ASU/NASA Space Grant Program  When you connect a wire between negative side to the positive terminal, the electrons will flow from negative to positive terminal.  Connect a load to the battery using a wire and load could be light bulb, a motor, or an electronic circuit like a radio.  A chemical reaction produces the electrons inside the battery and this chemical reaction (the battery's internal resistance)controls how many electrons can flow between the terminals.  Electrons flow from the battery into a wire, and travel from the negative to the positive terminal for the chemical reaction to take place.

ASU/NASA Space Grant Program Conclusion  Since the first battery was created by Alessandro Volta in 1800, it became our steady travel companion --- it helps call a friend; it expands our workplace beyond four walls; and it supports critical missions for people in need.  There are different types of batteries produced for a wide variety of applications ranging from storing solar power for satellites in space, to powering heart pacemakers fitted inside people's chests, to powering computers, iPods and etc.  The mechanism of the battery; its structure, components of the system, its function and importance that illustrates which battery chemistry is most appropriate for each application.  The future batteries
